For safety cable data and procedures refer to the SPM TASK 70-42-08-400-501.
Safety the threaded fasteners in this TASK with CoMat 02-274 SAFETY CABLE KIT or CoMat 02-275 SAFETY CABLE KIT for the ATA Chapter/Section/Subjects which follow:
A1 series engines: | ||
71-51-41 | 71-52-43 | 72-41-34 |
73-22-49 | 75-23-49 | 75-31-42 |
75-31-43 | 75-32-42 | 75-00-49 |
After assembly apply CoMat 07-038 AIR DRYING ENAMEL to any damaged surface protection, joint flanges and attachment parts. Use the correct color of air drying enamel. Refer to the SPM TASK 70-38-21-380-501.
The number for each radial location must be identified in a clockwise direction. These start at the engine top position when you look from the rear of the engine, unless stated differently in the procedure.
Transportation covers/blanks must not be removed until immediately before installation of the components.
Do not remove the special plastic caps from electrical connections until immediately before installation. This will give protection from unwanted material.

During the installation procedure make sure the harnesses are held temporarily along their different lengths. Always install the datum clip positions when you install each electrical connector. This will give correct installation of the different harnesses, prevent too much strain on the electrical connectors and give the necessary drip loops (the drip loop makes sure moisture or fluids do not go in to the electrical connector).
Because of the differences between the harness diameters, the specified clip could be too large or too small. You can use a clip from a range of six clips that have the same part number. If the harness diameter is between two of the clips in the range, use the larger clip. When you do this use CoMat 02-148 ADHESIVE TAPE (ELECTRICAL) to increase the harness diameter.
For the data on the electrical connectors refer to the SPM TASK 70-43-00-400-501 and the SPM 70-43-01-400-501.
For the data on the installation of the open wire harness refer to the SPM TASK 70-43-02-400-501.

A minimum clearance of 0.100 in. (2.54 mm) is necessary between the EEC harness ELECTRICAL HARNESS-LIGHT DUTY-EEC HARNESS-CORE (71-52-43, 01-005) and the tubes in the area shown. Refer to Figure.
To check the clearance, push the harness with a light pressure of the thumb then release. The harness must spring back and give the minimum clearance. The harness must not move through the adjacent clips, refer to Step.
Measure the clearance between all the different harnesses and the engine parts.
If the primary harness, the wire bundle breakout or a different harness touch each other they must be attached to each other. Refer to Step. The bundles must not move in relation to each other.
Examine the harness routing.
SUBTASK 72-00-40-220-085 Measure the Harness Clearances and Examine the Harness Routing
Attach the wire bundle breakout to the primary harness with CoMat 02-159 LACING TAPE so they do not move in relation to each other.
